FTL Based 4stage CLA Adder Design with Floating Gates

Low-voltage and low-power circuit structures are substantive for almost all mobile electronic gadgets which generally have mixed mode circuit structures embedded with analog sub-sections. Using the reconfigurable logic of multi-input floating gate MOSFETs, 4- bit full adder has been designed for 1.1V operation., Multi-Input Floating Gate (MIFG) transistors have been anticipating in realizing the increased functionality on a chip. A multi-input floating gate MOS transistor accepts multiple inputs signals, calculates the weighted sum of all input signals and then controls the ON and OFF states of the transistor.
